Abstract
A hoop for a safety cage assembly of a ladder includes a rigid arcuate band having a first face, a second face, a first end and a second end. Each of the first end and the second end are secured to a ladder. A plurality of keyhole openings extend through the band between the first face and the second face. A plurality of detachable tubing clamps are provided. Each of the tubing clamps has tubing receiving jaws defining a tubing receiving opening with an axis. The tubing receiving jaws have an exterior mounted projecting attachment key. In a first orientation, the attachment key passes freely in and out through a selected one of the keyhole openings in the band. In a second orientation, the attachment key is locked within the selected keyhole opening and the tubing receiving jaws are oriented with the axis of the tubing receiving opening positioned transversely in relation to the band.
